The fax machine is a symbol of obsolete technology long superseded by computer networks – but faxing is actually growing in popularity.

Four years ago, I wrote a history of 160 years of faxing, saying my book covered “the rise and fall of the fax machine.” The end I predicted has not yet come: Millions of people, businesses and community groups send millions of faxed pages every day, from standalone fax machines, multifunction printers and computer-based fax services. It turns out that in many cases, faxing is more secure, easier to use and better suited to existing work habits than computer-based messaging.

Businesses often use faxes

Faxing remains alive and well, especially in Japan and Germany – and in major sectors of the U.S. economy, such as health care and financial services. Countless emails flash back and forth, but millions of faxes travel the world daily too.

A worldwide survey in 2017 found that of 200 large firms, defined as companies with more than 500 employees, 82 percent had seen workers send the same number of, or even more, faxes that year than in 2016. A March 2017 unscientific survey of 1,513 members of an online forum for information technology professionals found that 89 percent of them still sent faxes.

The persistence of faxing – and the people who send faxes – is in part because the fax industry has adapted to accommodate new technologies. Fax machines still dominate, but both surveys suggested users were shifting to computer-based services, such as fax servers that let users send and receive faxes as electronic documents. Cloud-based fax services, which treat faxes as images or PDF files attached to emails, are also becoming more popular. These new systems can transmit faxes over telephone lines or the internet, depending on the recipient, handling paper and electronic documents equally easily.

Legal acceptance

Fax’s longevity also benefits greatly from reluctance – both legal and social – to accept email as secure and an emailed electronic signature as valid. Faxed signatures became legally accepted in the late 1980s and early 1990s in a series of legal and administrative decisions by state and federal agencies. The Electronic Signatures Act in 2000 also gave digital signatures legal power but institutional and individual acceptance followed only slowly – if at all.

Even parts of the federal government preferred faxes over email for many years thereafter. Not until 2010 did the Drug Enforcement Agency allow electronic signatures for Schedule II drugs like Ritalin and opiates, which comprised about 10 percent of all prescriptions. That meant a pharmacist could accept a faxed prescription but not one scanned and sent by email.

Faxing and medicine

Another reason faxing hangs on is because competing technologies are weak. The health care industry generates huge amounts of data for each patient. That should make it fertile ground for a fully digital record-keeping system, “where data can flow easily between patient, provider, caregivers, researchers, innovators and payers,” as Seema Verma, the head of the Centers for Medicare and Medicaid Services, put it in a speech earlier this year.

Comfortable inertia

One more personal factor preserving faxing is users’ reluctance to change. Small businesses who find that faxing meets all their needs have little reason to spend the money and effort to try a new technology for document exchange. Every company that prefers faxes inherently encourages all its customers and suppliers to keep faxing too, to avoid messing up existing ordering processes.

It’s important to remember, too, that fax machines and multifunctional printers with a fax capability provide an inexpensive backup capability in case of technical problems with an internet connection, or even a cyberattack, like the Russian attack on Estonia in 2007.

Absent a compelling reason or some management or government mandate, people often don’t change technologies. This is true beyond faxing: I drive a 2005 Camry. There are plenty of cars that are better in some way – safer, more fuel-efficient, more comfortable – but so long as the Camry passes state inspections and performs adequately, I can avoid the challenges and costs of buying a new car and learning how to use its new features.

Nevertheless, faxing continues because it remains better – cheaper, more convenient, more secure, more comfortable – than the alternatives for many people, businesses and organizations. Faxing will remain important until transmitting digital data becomes easier and more accepted. That could be a long way off, though. U.S. federal initiatives are trying to make medical records systems more compatible, but no one has yet been hired to take a key leadership position at CMS.

Eventually the older generation of people more comfortable with faxing than emailing will fade away. Until then, however, fax machines will whirl away.
